Technical field
The present invention relates to a kind of resistance spot weld, especially a kind of resistance spot-welding machine with floating welding heads.
Background technology
Resistance spot welding is a large welding method in electric resistance welding, is also important solder technology in welding field.Common resistance spot weld comprises upper and lower two soldering tips, and its lower soldering tip is fixed on support, and on it, soldering tip is arranged on an elastic rod, and a cylinder is housed above upper soldering tip.During welding, workpiece is positioned by cylinder, upper soldering tip to be imposed on downforce on lower soldering tip, itself and lower soldering tip is closed up and clamping work pieces, and then bestow electric current to soldering tip, and the electric current workpiece fuel factor that has a resistance of flowing through makes solder joint place's metal alloying and realizes welding.The conventional, electric-resistance mash welder is because lower soldering tip is fixed, so it can only provide a fixing working face (namely descending the upper surface of soldering tip), during welding, the solder side of workpiece must be concordant with this working face, just can reach accurate welding.But the location of this workpiece is difficult to accomplish perfectness, and particularly concerning need to be with mould fixedly the workpiece of solder joint, workpiece will be located together with mould, and this is easy to form location (being the working face that the solder side of workpiece exceeds welding machine).If can not accomplish accurate location (supposing that the solder side of workpiece surpasses the working face 2mm of welding machine), when upper soldering tip applies welding pressure and during clamping work pieces, will first make part deformation, and then be pressed on solder joint, like this, will cause solder joint to depart from, affect the quality (product defect that namely causes because solder joint is inaccurate) of postwelding workpiece, this does not allow to be permitted for accurate spot welding, so the conventional, electric-resistance mash welder is not easy to accomplish accurate spot welding.Moreover the conventional, electric-resistance mash welder requires also to be difficult to make it to be melted into flexible automatic production line or assembly line to the harshness of workpiece location, can not satisfy the needs of automated production.
Summary of the invention
The objective of the invention is provides a kind of resistance spot-welding machine with floating welding heads for the problem in prior art, makes soldering tip can automatically adapt to workpiece solder side residing position when clamping closing up, to satisfy the requirement of accurate spot welding.
For achieving the above object, technical scheme of the present invention is as follows:
it has vertical support, upper soldering tip, lower soldering tip, connect firmly the upper soldering tip mount pad that a level is stretched out on the top of described vertical support, it is characterized in that: a pair of vertical guide stem is arranged on described upper soldering tip mount pad by linear bearing, a welding pressure cylinder is installed by a cylinder mounting plate in upper end in described a pair of vertical guide stem, a slide block is arranged on described upper soldering tip mount pad by a pair of vertical guide rail, described upper soldering tip is arranged on a conducting block, described conducting block is fixed on described slide block by trip bolt and insulation system, the cylinder bar of described welding pressure cylinder links by a universal joint and joint and described slide block, lower soldering tip installing plate, insulation board and lower soldering tip conductive plate are housed successively in the bottom of described a pair of vertical guide stem, and they have upper and lower the floating of the fastening bolt of insulation sleeve and a pair of stage clip and a pair of extension spring to be bound up on the lower end of described a pair of vertical guide stem by cover, and described lower soldering tip is arranged on lower soldering tip conductive plate.
Further improved technical scheme of the present invention is as follows:
Described a pair of vertical guide rail adopts the pair of cross roller guide rail, and this pair of cross roller guide rail is arranged in a perpendicular grooves of soldering tip mount pad front end face, also is provided with this to a pair of pretension voussoir of crossed roller guide rail in this perpendicular grooves.
Can find out by technique scheme, the present invention is arranged on a pair of vertical guide stem on upper soldering tip mount pad by linear bearing, and the cylinder body of welding pressure cylinder is arranged on the upper end of described vertical guide stem, lower soldering tip is bound up on the lower end of vertical guide stem by upper and lower the floating of fastening bolt, stage clip and extension spring, upper soldering tip is arranged on upper soldering tip mount pad by a pair of vertical guide rail, and links with the cylinder bar.During welding, the cylinder bar promotes soldering tip and moves down, and lower soldering tip can move down limited and pulls by vertical guide stem during jack-up cylinder body and move at upper soldering tip, thereby realizes that the upper and lower of lower soldering tip floats.Realization due to the upper and lower float function of lower soldering tip, therefore no matter which position the solder side of workpiece is positioned at, as long as this position is between two soldering tips, soldering tip can be implemented adaptability and clamp, completely abolish the harsh requirement to the workpiece location in high-precision welding of conventional, electric-resistance mash welder, also overcome the shortcoming that workpiece in the conventional, electric-resistance pinpoint welding procedure is subject to welding pressure generation deformation.The present invention is skillfully constructed, and operation precision is high, has guaranteed that spot welding is accurate, can satisfy the requirement of accurate spot welding fully.Moreover, due to the realization of above-mentioned soldering tip self adaptation clamping function, make this welding machine can be fitted in easily different flexible automatic production lines or assembly line, form line body auto station, satisfy the needs of automated production.It is that vertical guide rail has adopted the crossed roller guide rail that the present invention further improves, and it can make the clamping action of soldering tip and lower soldering tip more stable, and motion process is more accurate.
